  • 2 cups water
  • 1/4 cup castile soap
  • 10-15 drops essential oil (optional)


  • Spray bottle
  • Funnel (optional)


  1. Add the water to your empty spray bottle. A 16 oz bottle is a good size.
  2. Use a funnel to slowly pour in the castile soap. The bottle should be about 3/4 full now.
  3. Add 10-15 drops of your favorite essential oil if you want a nice scent. Good options are lemon, lavender or tea tree oil.
